Description

Forged steel (butt-welded) fixed ball valve 5

The Forged Steel Butt‑Welded Fixed Ball Valve combines a robust forged steel construction with a full‑bore or reduced‑bore design that meets the demands of high-pressure systems in critical industries. Designed per API 6D and ASME B16.34 standards, this valve supports Class 150–2500 ratings and offers sizes from ½″ to 4″ (DN 15–100), accommodating both carbon steel and stainless steel materials, such as LF2, A105, 304, and 316L . The butt-weld connection ensures a leak-proof weld and compact installation, perfect for steam, gas, and cryogenic or high-temperature service lines where threaded or flanged connections are impractical .

This fixed ball valve has a solid stainless steel ball mounted within a forged body. Its floating ball design allows downstream pressure to press the ball into the seat, ensuring bubble-tight shut-off under variable loads. The fixed trim features include PTFE or PEEK seats, blow-out-proof stem, and anti-static devices, while fire-safe options comply with API 607/6FA and API 6D requirements . A three-piece configuration with bolted body or sealed bonnet allows easy access to internal parts for maintenance without removing the entire valve from the line

This valve operates with a simple quarter-turn, compatible with manual lever, worm-gear, pneumatic, or electric actuators thanks to its ISO 5211 pad. The full-bore configuration minimizes pressure drop and maximizes flow—ideal for high-flow applications like oil, gas, steam, and process liquids. Materials meet stringent specs—from ASTM A105 to exotic alloys like Hastelloy—ensuring durability in high-stress environments, with temperature ranges from cryogenic to 450 °C depending on seat selection .

Valve testing covers strength and seat-tightness per API 598 and EN 12266‑1 standards, and each unit undergoes factory inspection to guarantee reliability Fivalco+10JSC+10JD Valves+10. The compact butt-welded design maintains system integrity under thermal cycling and pressure changes. The rugged forged body withstands pipeline thrust and vibration, while anti-static features prevent ignition risks.

Ideal for high-pressure systems, this valve is favored over gate or globe valves because it offers faster operation, lower torque, and maintenance efficiency. It excels in on-site welding installations, minimizing footprint and eliminating potential leak points. The fixed ball and robust seating mechanism ensure consistent performance under extreme conditions.

Engineers choose this valve for critical duties in petrochemical, refinery, LNG, power generation, and industrial gas processing plants where safety, flow capacity, and reliability are paramount. Whether used in steam headers, high-pressure air lines, or fluid transport systems, the Forged Steel Butt‑Welded Fixed Ball Valve delivers dependable service with minimal downtime and operational efficiency.
